Vintage racers know all to well the difficulty there can be when it comes to finding appropriate tires for the race track, as the odd rim sizes of classic motorcycles are often outside the sizing parameters of good modern sticky tires. This leaves many racers using street-focused tires for their racing needs, but that could all come to an end, as Metzeler is expanding its Racetec RR Range to include 18-inch wheel sizes. Going forward from today’s announcement, the Metzeler Racetec RR DOT race tire will come in the company’s K1 compound (Metzeler’s softest compound), in the following sizes: 110/80-ZR18 (58W) front, and 150/65-ZR18(69W) & 160/60-ZR18 (70W) rear tires.

For reasons beyond our imagination and comprehension, the failed business experiment that was the Skully AR-1 helmet has been revived by new investors. Sending out a blast to the “Skully Nation” email list, the brand’s new owners Ivan and Rafael Contreras, have announced their plans to revive this seemingly dead project. One can barely fathom why someone would want to continue a project that so obviously was doomed to its own failure, and that also so grossly betrayed the goodwill of the motorcycle community; and yet, here we are, with Skully Technologies taking over where Skully, Inc. left off. The presumption of this news is that the new management hopes to bring the AR-1 helmet, with its heads-up display technology, to market.

The Nike Air Force 1 shoe is perhaps the most iconic piece of footwear ever created. It spurred an entire industry of sneakerheads – people who collect and trade shoes – and the Nike AF1 is one of the most collectible items for this genre of collector. So, it’s not surprising that there is industry buzz about a new Nike Air Force 1 being created. With each release, Nike has kept AF1 brand in line with its urban roots, where playing basketball on the street gave rise to young kids who would dream of following their heroes, like Michael Jordan, onto the courts of the NBA. Now having more of a cult following, Nike has been branching out with its AF1 offerings, and last month the sport brand debuted a special AF1, which pays tribute to Baltimore’s 12 O’Clock Boys.

Two labor unions have ended a partnership agreement with Harley-Davidson, citing differences with how the Bar & Shield brand handles staffing issues at its factories (Harley has been accused of replacing hourly union workers with temporary seasonal workers). The move comes after a meeting on Monday, which saw leaders from the International Association of Machinists & Aerospace Workers (IAM), United Steelworkers (USW), and Harley-Davidson President & CEO Matt Levatich unable to agree on how to handle staffing issues going forward. While the disagreement ends an accord that has existed between the unions and Harley-Davidson for the past two decades, it does not affect the collective bargaining agreement that the unions have with Harley-Davidson, which has been incorrectly reported elsewhere.

Say what you will about American politics, but the US House of Representatives has passed the “SELF-DRIVE Act” (H.R. 3388) – a bipartisan bill that would open up autonomous vehicle regulation for manufacturers. The big advantage of the SELF-DRIVE Act is that it would supersede the varying and ad hoc state rules that manufacturers must currently adhere to while developing their autonomous platforms. The bill would also do away with some safety standards put in place for vehicles with drivers, such as where the steering wheel and foot pedals must be located. Lastly, the SELF-DRIVE Act would require the Department of Transportation (DOT) to research and develop a way of conveying to consumers the level of automation a vehicle possesses.

In early 2016, I was fortunate enough to ride the revamped and Euro4 version of the MV Agusta Brutale 800. On paper, the Brutale 800 lost power and gained weight, but the reality is that MV Agusta improved upon already one of its best-selling machines, in subtle and clever ways. Now a year-and-a-half later, the 2017 MV Agusta Brutale 800 is finally available in the United States, and I have been reunited with one of the best street bikes on the market. Spending almost all of last month with this motorcycle again, it is clear that not much has changed from a rider’s perspective, though internally improvements have been made to some of the weaker elements of the design, like the sprag clutch and valve train. While not much has changed with this year’s edition of the MV Agusta Brutale 800, I am mostly fine with that.

What happened when Valentino Rossi crashed? How serious is his injury? When will he be back? Who will replace Rossi, if he doesn’t return at Aragon? And what does Yamaha think of Rossi’s training methods? Yamaha boss Lin Jarvis spoke to a small group of journalists at Misano on Saturday morning, to answer these questions and much more. Jarvis knew about the accident very shortly after it had happened. “I knew before he got to the hospital,” Jarvis told us. “Albi [Tebaldi] called Maio Meregalli as soon as he got the news that Vale was on the way to the hospital. Maio called me straight away.” The good news was that Rossi’s injury was not as bad as the last time he broke his leg, at Mugello in 2010. “It’s much less serious,” Jarvis told us, “but probably just as irritating.

While the launch of the Ducati’s Desmosedici Stradale V4 engine and leaked photos of the Ducati Panigale V4 dominated the news on Thursday, Aprilia Racing was quietly changing the sport of motorcycle racing, as it debuted an augmented reality helmet that its mechanics will wear in MotoGP. Aprilia has partnered with DAQRI and Realmore to make the augmented reality helmet come to fruition – DARQI is making the hardware, while Realmore is responsible for the software. As followers of augmented reality (AR) tech may already have guessed, Aprilia Racing’s AR helmet will allow its mechanics to visualize and share information, overlaid on what is occurring in the pit box. Aprilia Racing sees two major scenarios where using augmented reality could be of benefit.

Apparently today is Ducati Day, as news continues to come from Italy about the Ducati Panigale V4 and its Desmosedici Stradale engine. Ducati has already spilled the beans on the new 210hp V4 engine it has been developing for its next superbike, but now we also get more spy photos of the Panigale V4 that will carry it. These latest spy photos show quite clearly the 2018 Ducati Panigale V4 that will debut later this November, at the EICMA show in Milan. Ducati CEO Claudio Domenicali confirmed the Panigale V4 name today, and for our A&R Pro members, we have gone into a lengthy analysis as to why Ducati is choosing to keep the styling and name of this machine so similar to the previous model.

Hello and welcome to a new era of Ducati motorcycles, which is starting with a very special engine. Named the Desmosedici Stradale, this road-going version of the company’s MotoGP power plant is what is going to power Ducati’s next superbike, the Ducati Panigale V4. Debuting today in Misano, at a special event ahead of the San Marino GP, the mystery around the Desmosedici Stradale engine has finally be revealed, to the tune of 210hp (@ 13,000 rpm) and 88.5 lbs•ft of torque (@ 12,250 rpm). Dropping details on the 90° V4 engine with desmodromic valves, we now know that Ducati will continue to play the displacement game with its superbike, as the street version of the Panigale V4 coming with a 1,103cc displacement.

Asphalt & Rubber was on-hand yesterday for first testing of the SWIGZ.COM electric race bike, which is being put together and piloted by Chip Yates and his crew. Getting blessed with a perfect California winter’s day, we only had to wait for Infineon Raceway, which is becoming the venue of choice for electric motorcycle race teams, to dry out from the previous night’s rain before the sunny 54° F temperature allowed Yates to get on the track. Taking eight laps in the afternoon, Yates ran the SWIGZ bike without the highly anticipated front KERS components, which will be the same configuration the bike will use when racing against the gasoline powered v-twins in the WERA Pirelli Sportsman Heavyweight Twins Superbike class later in January.

With the SWIGZ bike showing more than ample power in the straightaway, the electric race bike “exceeded all my expectations” said an enlighted Yates when he finished his last session. The first shakedown test on a track, Yates was also pleased with the bike having no mechanical failures during the sessions, giving him a vote of confidence for January’s race, which will see the SWIGZ race team contend against Ducati 1198 and KTM 1190 RC8 R superbikes.

After first seeing the TTXGP and then FIM e-Power race series lower their maximum bike weights to 250kg, thus barring the 266kg SWIGZ race bike from competing, Chip Yates and his SWIGZ.COM race team seem to be making the best out of a bad situation, and have announced that they will compete in the WERA Pirelli Sportsman Heavyweight Twins Superbike class race being held at California Speedway on January 9, 2011.

Promoting an advanced KERS system, Yates has been touting his 194hp electric race bike as being comparable to gasoline-powered supersport machines, and now he will have the opportunity to prove that point on the track. With performance parity to internal combustion engine such an important issue with electric motorcycles, SWIGZ is the first team to take on the old guard head-on, with this first race being the first public working exhibition of the SWIGZ KERS design.

Last week I had a chance to ask Chip Yates some questions over email about the progress of the SWIGZ.COM Pro Racing Electric Superbike program. Chip’s responses tell us his team’s ambitious performance goals are on track and they are quickly signing on sponsors. SWIGS.COM Pro Racing remains the only electric motorcycle race team to put the cards on the table for 2010 in regards to target performance.

In late 2009, Chip announced he had assembled a team including two MIT grads turned aerospace engineers to develop an electric superbike to compete in the TTXGP race series. The press release mentioned some very impressive and somewhat controversial goals for the SWIGZ.COM bike including the ability to turn AMA SuperSport lap times (GSX-R600) and a KERS system to return braking energy back to the battery.

Since the announcement, the electric motorcycle racing landscape has changed dramatically with the entrance of the FIM e-Power series and the TT Zero race replacing TTXGP at the Isle Of Man. Some races have conflicting schedules that will force teams to choose one event or the other. Chip explains what series the team will run and which they will not. Unfortunately the team is not releasing any of the electric drive specs and vendors yet but some details should be announced next month.
